EFFECT OF Ca and Mg ON MECHANICAL PROPERTIES AND HOT WORKABILITY OF SUPERALLOYS |
| |
| Abstract: | The effect of single or multiple addition of trace element Ca and Mg on mechanical properties and hot ductility of the wrought and casting nickel base superalloy has been investigated. The results show that the creep rupture life, high temperature tensile ductility and hot ductility of the superalloy can all be improved when a proper amount of Mg or Ca+Mg is added. |
